The most important weapon at a wrestler's disposal is something that can be gained gradually over time, but also lost in one single moment, never to be returned.
Credibility. No wrestling career can survive without it.
If a wrestler is strong in a particular area of his performance, but weak in others, there are ways to make sure that his weaknesses don't become detrimental to his character.
For instance, Daniel Bryan is not the strongest performer on the mic, but he makes up for it with his exceptional ability in the ring. For the Miz, the exact opposite is true.
The Great Khali is awful at everything, but has an imposing physique. He looks—at least to the casual observer—as if he should be a major threat. This makes him a credible—even if he's utterly incompetent—performer.
Over the years, there have been some spectacular occasions of credibility disappearing faster than a Kofi Kingston push.
Wrestlers, especially early in their career, can take a degree of humiliation and still recover. When the Miz accepted a blindfold from Layla and then unwittingly got a lap dance from Big Dick Johnson, not many would have believed he would become a future World Champion.
Others are not so fortunate.
Here are five individuals whose careers died in one moment of madness.
